I'm on the last question of an assignment and stuck. .

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

The function below is written in vertex form or intercept form. rewrite them in standard form and show your work. y = (x+4)(x+3)

Look at the figure xyz in the coordinate plane. find the perimeter of the figure rounded to the nearest tenth.
